Analysis Of Surface Modification On Coal Pyrite

Bacterial conditioning prior to froth flotation has been used to enhance the separation of pyrite from naturally oxidized coal.The pyrite surface in the coal slurry was selectively made more hydrophilic by adapted thiobacillus ferrooxidans bacteria, thereby depressing the floatability of pyrite, but not that of coal.After bioconditioning and removal of the bacterial culture, the coal slurry.
